I have had a problem with my brakes pulling to the right. I replaced both front calipers and pads and bleed and flushed the system. still pulled.
I replaced both tie rods, idler arm and had the Recall done on the relay. I also checked to make sure the bearings were good and they were. The Runner would track just fine driving down the road until I hit the brakes and then HOLY SH%!

I was ready to just stick a gas soaked rag in the fuel tank and then I discovered the problem. :pat: The four bolts that hold the Master cylinder to the brake booster where very loose! I tightened them all up and BAM! a test drive revealed that indeed it was fixed! I slam on the brakes no hands on the wheel and straight she go's! I am very happy to say the least ! I have had to put up with this thing for far to long!

I just wanted to share this with the yota community incase there are any doe does like me out there.

 

wow...that might be the cure to my problem...only mine doesn't sound as bad as yours...mine is just after the brakes get hot...then she pulls to the right with a vengance....
